Fig. 8 is the top view of ladder block:
Location ladder block 1-6 establishes 2～6 steps, the present embodiment is to establish 6 cascaded surfaces as example along block guide rail direction, as J1～J6, the poor L1 of the ladder width of each step, L2, L3, L4, L5 determine the distance between left-right longeron location-plate 1-11, and be corresponding with the longeron stand out of each vehicle of locate.
Thickness S1, the S2 of the ladder of location ladder block 1-6, S3, S4, S5 are determined by the stroke that corresponding block drives cylinder 1-1,1-2,1-3.
Girder space detent mechanism 1 major function is to realize the movement of ladder block, and different cylinder stroke combinations realizes that the ladder block moves different distances.
Longeron displacement governor motion 2 major functions are to realize the movement of girder space detent mechanism 1, thereby the location spacing is adjusted, and realize displacement.Two bearings that drive cylinder 2-4 are fixed on the clamp base 3 of chuck body, and horizontal anomalous movement axle 2-3 is arranged in the pilot hole of inside and outside support plate 2-1,2-2, by drive cylinder 2-4 stretch realize that movable axis moves around along the direction of B.It moves until horizontal thimble 2-6 stops when contacting with ladder block 1-6; And the ladder block 1-6 of girder space detent mechanism 1 can move separately on the direction of A shown in figure, and its moving range only is subjected to three blocks to drive the Stroke Control of cylinder.
Girder space detent mechanism 1 is suspended on the horizontal anomalous movement axle 2-3 of longeron displacement governor motion 2, the Telescopic-cylinder of girder space detent mechanism 1, cause vertically moving of ladder block 1-6, the cylinder of longeron displacement governor motion 2 shrinks, drive girder space detent mechanism 1 together along with the movable axis transverse shifting, horizontal thimble 2-6 is contacted with ladder block 1-6 step surface, realized the location.Because girder space detent mechanism 1 has three groups of cylinders, each flexible combination is different, cause the ladder block to vertically move the position of arrival different at every turn, realize that each horizontal thimble 2-6 contacts from the different cascaded surfaces of ladder block, the stroke of movable axis transverse shifting is different, has so just realized the multiple spacing location of locating piece.
Drive the flexible of cylinder by block, ladder block 1-6 can slidably reciprocate along diagram A direction on slide rail 1-7; Three blocks drive the flexible combinations of states difference of cylinder, and the distance that the ladder block moves is also just different, thereby realizes multistage adjusting.
As shown in Figure 1 and Figure 2: under the beginning state, the first block drives cylinder 1-1 cylinder bar and entirely stretches out, and it is zero that the cylinder bar of the second block driving cylinder 1-2 and the 3rd block driving cylinder 1-3 stretches out, and location ladder block 1-6 is at maximum L0.
The spacing handoff procedure of whole mechanism is as follows: as shown in Figure 1 and Figure 2, whole platform floor 5 is placed on fixture, by two longerons 4 and longeron raceway 6 contact support platform floor 5(herein fixture raceway 6 be the part of whole clamp base, play the effect of supporting platform floor 5, its idler wheel surface contacts bottom longeron, do not describe in detail in the drawings, only with dashed lines draws its approximate location); Longeron 4 is placed on fixture raceway 6, and longeron location-plate 1-11 contacts with longeron 4 outsides, plays the effect of restriction two girder spaces.By adjusting the spacing of longeron location-plate 1-11, can control the spacing of left-right longeron.
Whole location ladder block 1-6 handoff procedure divided for 2 steps:
As Fig. 5～shown in Figure 9, the 1st step: realize that the A of location ladder block 1-6 is to movement.as shown in Figure 3: the first block driving cylinder 1-1 cylinder bar of girder space detent mechanism 1 stretches out at this moment, the cylinder bar that the second block drives cylinder 1-2 and the 3rd block driving cylinder 1-3 shrinks (cylinder location as shown in Figure 3), the corresponding ladder stop location of horizontal thimble 2-6 is cascaded surface J6 shown in Figure 5, when switching spacing, the cylinder bar that the 3rd block drives cylinder 1-3 stretches out (this moment one, the cylinder bar that three blocks drive cylinder all stretches out, the cylinder bar that the second block drives cylinder shrinks), shown in ladder block 1-6 edge, location, A direction displacement S6(S6 is the stroke of cylinder C), this moment, horizontal thimble 2-6 broke away from the cascaded surface J6 of location ladder block 1-6, J5 is relative with cascaded surface, but also not contact, namely become Fig. 6 state by Fig. 5.
The 2nd goes on foot as Fig. 5: horizontal anomalous movement axle 2-3 is under the contraction that drives cylinder 2-4, pull girder space detent mechanism 1 to B to motion, until the cascaded surface J5 of location ladder block 1-6 contacts with horizontal thimble 2-6, in this process, whole girder space detent mechanism 1 is together along B shown in figure to movement; Until end in contact before the cascaded surface J5 of location ladder block 1-6 and horizontal thimble 2-6, under horizontal thimble 2-6 effect, horizontal anomalous movement axle 2-3 stops movement, girder space detent mechanism 1 location positioning at this moment, longeron location-plate 1-11 location positioning.Longeron location-plate 1-11 is L5 along B direction move distance, namely becomes Fig. 7 state by Fig. 6.Left-right longeron location-plate 1-11 spacing becomes (L0-2*L5) by L0, has realized the switching of location spacing.
The relative position of whole process location ladder block 1-6 and horizontal thimble 2-6 changes as shown in Figure 9:
When three blocks drive the variation of Telescopic-cylinder combinations of states, location ladder block 1-6 is respectively along the A S1-S6 distance of moving, horizontal thimble 2-6 contacts with the corresponding cascaded surface J1 that locates ladder block 1-6～J6 respectively, longeron location-plate 1-11 has realized the switching of location spacing respectively along the B L1-L5 distance of moving.With stretching all by electrical control of upper cylinder, realized automatically switching fast of location spacing.And longeron location-plate 1-11 spacing by location ladder block 1-6 and horizontal thimble 2-6 contact control, not affected by the stroke of cylinder, unstable at air pressure, when cylinder stroke is not in place, also can realize the accurate control of locating piece spacing.
When three blocks drive the different combination of cylinder, corresponding relation such as the following table of location ladder block 1-6 and horizontal thimble 2-6 contact-making surface and longeron location-plate 1-11 spacing:
| Sequence number | Cylinder state | The ladder block cascaded surface | The locating piece spacing | |
| 1 | One stretch, two, three | J6 | L0 | |
| 2 | One, (three) stretch, two contractings | J5 | L0-2*L5 | |
| 3 | One, two stretch, three contractings | J4 | L0-2*(L5+L4) | |
| 4 | One, two, three stretch | J3 | L0-2*(L5+L4+?L3) | |
| 5 | One, three contractings, two are stretched | J2 | L0-2*(L5+L4+?L3+?L2) | |
| 6 | One, two contractings, three are stretched | J1 | L0-2*(L5+L4+L3+L2+L1) |
